Pros:

price

Cons:

not really a ring flash

Doun't buy this if you want those distinctive ring shaped highlights in eyes. This is really two small flashes that overpower the ring shaped diffuser so you get two spots rather than a doughnut catchlight. Worse, you get two distinct shadows behind the subject. On the good side you can freely rotate the unit so the two shadows can be placed where you want them and the up to 8:1 ratio control allws a lot of exposure options. I built a secondary diffuser in front of the unit which spread things out a lot but cut down on the already low enough power. This is a good macro tool for the money. It is really not suitable for non-macro ring uses. It works wirelessly with my Sigma EF500DG Super and makes quite a versitile rig in that manner.

Pros:

Low price, decent construction

Cons:

NOT a ringflash, rotation around lens axis can't be locked

This flash is a relatively cheap macro flash and, as such, will be and interesting option for aspiring macro photographers.

It is not a ring-flash, though. There are two short flash heads instead of longer curved ones. If the the lack of shadows is critical to you, you'd better look elsewhere.

On the other hand, you can adjust the power on the heads individually and get a bit of the same effect that twin flash gives. Unfortunately, the heads are not adjustable and they are a bit too close to each other for the effect to work well with longer focal lengths.

It is possible to adjust the angle of the heads by rotating the ring, but there is no way to lock the rotation - at least originally. Double sided adhesive in the groove should solve that.

One more thing to note is that this flash sits further away from the lens than Canon's (don't know about other systems) own. That may become critical at high magnifications with 50-60 mm macro lenses.

If the down sides above are not serious for you, this flash will get the job done for a decent price.

Pros:

nice even light for macro subjects

Cons:

requires adapter tubes for different lenses

Great low-cost option for macro lighting. I used this with a Canon 100/2.8 + 20D and with a Canon Powershot G5 and got excellent results.
